Privacy Policy

Last updated: February 21, 2026

This Privacy Policy explains how Techsolid Automation Limited ("we", "us", "our") collects, uses, and protects information when you use rungs.dev and studio.rungs.dev (the "Service").

What We Collect​

Analytics Data​

We use PostHog (EU instance) to understand how the Service is used. PostHog may collect:

• Usage events — actions such as creating, importing, exporting, and sharing AOIs; starting simulations and tests; editing sessions
• Session recordings — anonymized replays of how you interact with the interface
• Device and browser information — browser type, operating system, screen size, and technical identifiers
• Page views and navigation — which pages you visit and how you move through the Service
• Error and performance data — exceptions and timing metrics to help us improve reliability

Analytics data is processed in the European Union via PostHog's EU infrastructure (eu.i.posthog.com). While we do not require account registration, analytics and service providers may still process online identifiers and similar technical data.

Cookies​

PostHog sets analytics cookies to distinguish unique visitors and sessions. We do not use advertising cookies. We currently do not provide a cookie consent banner. You can block or clear analytics cookies using browser controls or privacy tools.

Search (Docs Site)​

The documentation site at rungs.dev uses Algolia for search. Algolia processes your search queries to return results. Do not include personal or sensitive information in search queries.

What We Do Not Collect​

• No accounts required — the Service does not require registration, login, or email addresses.
• No project data on our servers — your AOI projects are stored locally in your browser's localStorage. We never upload, access, or back up your project data.
• No payment information — the Service is currently free. If paid plans are introduced, payment processing will be handled by a third-party provider and this policy will be updated.

AOI Sharing​

When you use the optional Share feature, the AOI data you choose to share is uploaded to our database (hosted on Supabase) and made publicly accessible via a link. Shared AOIs are:

• Public — anyone with the link can view and fork the shared AOI
• Anonymous — shares are not linked to any user identity
• Size-limited — maximum 100 KB per shared AOI
• Rate-limited — to prevent abuse

You can share AOIs at your discretion. Do not share AOIs containing proprietary or confidential logic.

Shared AOIs may be used to operate, secure, and improve the Service, including developing, evaluating, and training machine learning and AI features. This applies only to AOIs you choose to share, not AOIs stored locally in your browser.

Data Storage and Retention​

Third-Party Services​

Your Rights​

You can:

• Clear local data at any time by clearing your browser's localStorage for studio.rungs.dev
• Opt out of analytics by using a browser extension that blocks PostHog (e.g., an ad blocker or privacy extension)
• Request data deletion by contacting us — we will remove or anonymize analytics data associated with your sessions where technically feasible

If you are in the EU/EEA, you have rights under GDPR including the right to access, rectify, or erase personal data. Contact us to exercise these rights.

Children's Privacy​

The Service is not directed at children under 16. We do not knowingly collect information from children.

Changes to This Policy​

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated "Last updated" date.
